I have installed Ubuntu 11.04 and battery life decreased by 2 times. Powertop documentation says that there should be 3 wakeups per second, I have 800-900. I think it's very strange because I didn't touch any settings except for disabling nvidia graphic card.
How can i improve battery life?

Ah, good to know. What other browser do you suggest? In my experience Firefox takes a lot more CPU to render a page, so in addition to being slower, it uses more power for rendering. My gut feeling is that Firefox may still be more power-efficient, but it would be worth measuring.

Firefox has better results than Chrome in the bug report. In Phoronix the results are the opposite phoronix.com/…. Depends of the number of open tabs. I use Firefox7 in my netbook and the performance/consumption is very good (400 open tabs). A tip is use Panorama and other is change the preference "browser.sessionstore.max_concurrent_tabs" to 0.

And yes, Firefox will be more efficient and fast because to the actual works in GPU rendering.
